We live in an age where patches and updates are a daily occurrence, so it shouldn’t surprise you too much if you come across a recent release that includes a bug or two. In the case of Pikmin 3 and its demo, a glitch allows you to play more than you should.
As you could see in the video above, a series of glitches allow you to explore beyond what was allowed in the beta to reach a much more advanced area of the game. If you manage to do it, which is more difficult than you thought, you will be able to face Vehemoth Phosbatthe second boss of the game.
APerson13, the youtuber who uploaded this clip, says to beat the Vehemoth Phosbat it does indeed unlock an additional story, but because the game is still missing a few files, it’s still impossible to access.
